Abstract

PURPOSE:To delete a series of continuous characters or a pair of parentheses, etc. altogether by using a character discriminating means to change the types and the range of characters to be deleted. CONSTITUTION:The characters are supplied to a document memory by a character input instructing device (cursor). A character discriminating device is actuated by a deletion instructing device to discriminate the characters deleted out of the document memory by the deletion instructing device. Then a parenthesis deleting device, a sentence deleting device or a deleting device for characters of same type works to delete the parentheses out of the document memory. Thus it is possible to delete a series of continuous characters or the marks like the parentheses, etc. which are used in pairs altogether by means of a single deletion instructing device.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a character processing device capable of inputting and deleting characters and symbols. There was a character processing device that was capable of deleting characters in text.When deleting characters in such a device, generally, the character to be deleted was specified in the cursor list, and the character at cursor L was deleted by just one character. The conventional method was to delete a character.However, in reality, rather than deleting just one character, for example, tt'
It is necessary to use a bar to delete the middle part of a word, the middle part of a sentence, or both parentheses τ that are paired. In such cases, the conventional method of deleting one character is complicated, and we need to solve this problem. The disadvantage is that multiple deletion keys are required for this purpose.

[Problems to be Solved by Issuu 1] This book 55 1- compensates for the drawbacks mentioned above, and changes the object to be deleted depending on the type of character in 1-1.For example,
To provide a character processing device which realizes the operation of deleting consecutive uniform characters or brackets used in pairs all at once using one deletion key.

[L Il and operations for solving the problems] In the uninvented system, characters are input into a document memory by a character input instruction device as shown in FIG. The deletion instruction device causes the character recognition device to (@), and the deletion instruction device detects the sentence deleted by the deletion instruction device.
The characters in the given memory are classified by t'l, whereby the parenthesis deletion device or sentence deletion head or similar character deletion device operates to delete the parentheses in the sentence selection memory.

[τ Example] The present invention will be described in detail below with reference to the drawings.

FIG. 2 is a diagram showing an example of the configuration of the character processing device of the present invention.

The CPU (Central Processing Unit) executes the contents of the programs in the L order shown in Figures 5 to 7 contained in the ROM (Read Only Memory). Control. A keyboard KB is connected to this pass line, and character information input from this keyboard KB is supplied and stored via the pass line B to a document memory BSM located in a part of the random access memory RAM. To display the stored character information on the display fiLcD (liquid crystal display), select the font to be converted into a character code from the character generator CG controlled by the display controller 21LCDC via path line B according to instructions from CPtJ. and stores the font in the display memory LCDM of the display control device. The above statement is in the memory RAM! :In addition to the memory BSM, there is an area for temporary storage of CRLM$ indicating the cursor position. Printer PRT is the above statement,! ; CP the contents of memory BSM
This is a device for printing according to instructions from U.

Figure T3 is an enlarged detailed view of the keyboard of Figure 7. This white character key is a key for inputting normal characters, and the character code corresponding to the key entered here is as shown in the above sentence:
It is stored in the town memory and displayed on the LCD. The delete key is a key for deleting characters of the same type.

Figure 4 shows the document q memory B in RAM in Figure 2.
37m explanatory diagram of SM 0 sentence 8 memory BSM is a serial memory in which character information is stored and is configured in address order from the beginning, in order BSM (1), BSM (2)
---Generally expressed as BSM(i).

The operation of the embodiment of the present invention is shown in FIGS.
This will be explained with reference to the flowchart 1 of FIG. 7 and the example of FIG. 8.

When this device is powered on, it first proceeds to step sl. In step sl, space is cleared from the Bunzuki memory BSM in the RAM, the cursor is set to the beginning of the Bunzuki memory BSM, and the cursor position memory CRLM is initialized. Set to state.

After that, the process advances to step S2, and the state of waiting for a key input from the keyboard KB shown in FIG. move on.

Step S4 performs processing when a character key is operated. In the 7JSB diagram, when a character key is operated, the character code is stored in the text memory BSM corresponding to the cursor position memory CRLM. Thereafter, the cursor advances by one, and at the same time, the contents of the cursor position memory CRLM also advance by the air address.

Next, in step S6, a predetermined character code string (determined by the display capacity of the display unit) of the sentence and memory BSM is patterned by the character generator CG and displayed 471
The data is stored in the memory LCDM of the control device LCDC.

Step S5 performs deletion processing, which will be explained with reference to FIG. 6. First, in step 55.1, the character ``Bunten Memory'' not indicated by the cursor is determined. As a result, if it is a parenthesis, proceed to step 55.2, if it is ",", proceed to step 55.3, and if it is one sentence 'r, proceed to step 55.4.
Proceed to.

The j1 lesson of step s5.2 will be explained using the flowchart of FIG. 7 and the text example of χ in FIG. 10. First, proceeding to step s5.2.1, the direction of the parentheses of the cursor "-" is determined. As a result, as shown in Figure 1O (1), in the case of a left parenthesis, proceed to step s5.2.2 and search for a right parenthesis in the direction of the end of the sentence, then proceed to step s5.2.3 as shown in Figure 10. As shown in (2), delete the right parenthesis and move the character after it one character to the left. Further step s5.2
．． Proceed to step 6, delete the parentheses above the cursor, shift the following characters one character to the left, and move the cursor position one character to the left.

The result is the state shown in Figure 1o (3).

On the other hand, if the character at the cursor "2" is a right parenthesis as shown in Figure 10 (4), proceed to step s5.2.4 and search for a left parenthesis in the direction of the beginning of the sentence. Proceeding to step s5.2.5, the left parenthesis is deleted, subsequent characters are shifted one character to the left, and the cursor is also moved one character to the left. After that, proceed to step S5, 2゜6, and the result is 7j.
T, is in the state shown in Figure 10 (6).

Next, details of step 85.3 will be explained using the flowchart of FIG. 8 and the text example of χ in FIG. 11. First, proceed to step S5.3.1 and place [,j] to the left of the cursor.
14 M+1 whether exists or not. As a result, the 11th
If "," is black on the 7i: side of the cursor as shown in FIG. 1, the process advances to step s5.3.2, and then it is determined whether or not there is a character to the left of the cursor. As a result, if there is a problem, proceed to step s5.3.3 as shown in Figure 11 (
As shown in 2), delete the character to the left of the cursor and move the character after that one character to the left. Further step s5.3.
4i,'' advances and the cursor position also moves one character to the left.Furthermore, repeat the process from 1x on step s5.3.1.

As shown in Figure 11 (4), if there is a ``,'' to the left of the cursor, proceed to step s5.3.5, delete the ``1゜'' on the cursor, and move the following characters one character to the left. pack. The result is the state shown in FIG. 11 (5).

On the other hand, if the character "," to the left of the cursor is also black, as shown in Fig. 11 (11), proceed from step s5.3.2 to step s5.3.5 and proceed to step 111'A (9). It will look like this.

Next, explain step 55.4:>1m using the flowchart in Figure 9 and the text example for x in Figure 12.
do. First, the process proceeds to step s5.4.1, and it is determined whether the character on the cursor and the character type to the right are correct. the result,
As shown in FIG. 12 (1), if the character type is T, as in the case where the cursor j is l and the one on the right is 2, step s5.4
．． Proceed to step 2, and then delete the character to the right of the cursor and move the following characters one character to the left as shown in FIG. 12 (2). Furthermore, the process returns to step 55-4.1 and repeats the process.

As shown in FIG. 12 (2), if the character type of cursor L and the character type to the right are not equal to 7PL, step s5.4. L-
c Branch to step s5.4.3.

Delete the character on the cursor and move the following characters one character to the left. The result is the 121st ffl (3) state.

Note that in this example, only the parentheses 0 "" were used, but parentheses such as "FJ" and "Book ]" are also effective, and are used in English sentences.
Even marks such as “ do not detract from the gist of the present invention.

In addition, in this embodiment, the final mark of the sentence is only ".", but other marks such as "?", "!", or the period "," used in English can also convey the gist of the present invention. It doesn't damage it.

In addition, in this embodiment, the character types are only hiragana and katakana with one number, but of course other character types such as kanji and alphabetic characters, and even if uppercase and lowercase letters are separate character types among alphabetic characters, would spoil the purpose of the unreleased IJi. Not.

Furthermore, although the display device in this embodiment is an LCD (liquid crystal display), other display devices, such as a C
The use of RT (cathode ray tube) does not detract from the invention of /411'.

[Effect J iu As mentioned above, according to the uninvented invention, depending on the type of alphabetic character at the cursor j-, there is a bar that deletes a series of consecutive characters or parentheses used in pairs all at once. With one deletion instruction r step, 1°11 becomes 111f7.
